UNITED STATES PATENT OFFICE.

JOHN BURTON, OF GENEVA, ILLINOIS.

PROCESS OF MANUFACTURING SIZED PAPER.

SPECIFICATION forming part of Letters Patent No. 250,781, dated December 13, 1881.

Application filed J nne 6, 1881.

1'0 all whom it may concern Be it known that I, JOHN BURTON, a citizen of the United States, residing at Geneva, in the county of Kane and State of Illinois, have invented a certain new and useful Improvement in the Process of Manufacturing Sized Paper, of which the following is a specification.

The object of my invention is to produce a new sizing which will give a better body and finish to the paper and cheapeu its manufacture.

The nature of my invention consists in using glucose as a sizing in the manufacture of paper.

To enable others skilled in the art to understand how to use my process in the manufacture of paper, 1 will describe the same with particularity.

I take any of the ingredients that are used to make the paper-pulp and prepare it in the ordinary way of preparing paper-pulp, and I take glucose and put it in the pulp in about the same quantity that other materials that are now used for sizing are used; or I may apply the glucose for sizing and finish as the paper is passed through the rolls. The quantity of glucose that is used may be varied ac- (No specimens.)

cording to the quality of paper that it is desired to make and the character of the finish that is to be given to it.

I find that in manufacturing printing-paper that is used for newspaper purposes its quality is improved by mixing glucose with the pulp; but itv may be used in the manufacture 'of all kinds of sized paper in the same manner; and when it is desired to give a better finish and gloss to the surface of the paper the glucose may be applied as a sizing as the paper is passed through the rolls, in the same manner that other ingredients are now applied as a sizing to the paper.

Having thus described my invention, what Ielaim as new, and desire to secure by Letters Patent, is-- The manufacture of sized paper by the use of glucose as a sizing and mixing it with the pulp or applying it to paper as it is passed through the rolls, substantially as described.

JOHN BURTON.
